Australian manufacturers of period underwear have denied using “forever chemicals” in their products following a class-action lawsuit in the US, while experts say more research is needed into the compounds and their potential health impacts.

Thinx, a US manufacturer of menstrual hygiene products, announced last week that it had reached a settlement in a class-action lawsuit over allegations “regarding the presence of short chain per-and polyfluoroalkyl substances (‘PFAS’)” in its underwear.
